        Silicones are thermoset materials that have a chemical stucture based onchains of
        alternate silicone and oxygen atoms withorganic groups attachedthe silicone atoms.<br ><br >


       <img src="__STATIC__/images/tpe1.jpg" align="right" > Silicones come in many processable forms, including liquid silicone rubber(LIM or LSR),
        heat cured rubber(HCE or HCR) and room temperature vulcanized rubber(RTV). It comes in
        five gallon pails or 55 gallon drums and dose not require any
        roll milling or compounding. Liquid silicone rubber is fed to
        molding machines using self-contained meteringpumps,
        minimizing any opportunisties for contamination or
        non-deliberate off ratio delivery. In some cases, heat cured
        rubber peroxide cured silicones are still used due to properties
        achievable with customized compounding. This is particularly the case in automotive and
        electrical applications.<br ><br >

        Once a silicone material is molded, it forms a permanent shape and it can not be broken
        down into a reusable form for molding again, hence a thermoset designation. This feature,
        as well as a relatively high material cost, makes it particlularly important to get things right
        the first time for the processor. Cured silicone waste is commonly landfilled due to the lack
        of economically feasible uses.<br ><br >


        Silicone is a very popular material in body contact applications where its hypoallergenic
        nature is important. Many healthcare products which were once made from latex or natural
        rubber have been replaced with silicone for this reason.<br ><br >

        Silicone offers material stability over avery broad temperature range. It is able to be used
        continuously at 350-400oF with minimal change in physical or appearance properties.
        It remainsslastomeric and flexible at low temperatures. Typically down to -100oF.

        <div class="about_box_title"> What is TPE?</div>
        TPE stands for thermoplastic elastomer, which is also called thermoplastic rubber. TPEs are
        a class of copolymers that are a mix of polymers; most commonly a plastic and a rubber.<br >


        These copolymers allow for the TPE to have a blend of desirable physical and appearance
        properties. Common types of TPEs are TPO, TPV, SBC, TPU, COPE and COPA
        <img src="__STATIC__/images/tpe2.jpg" align="right" > In terms of performance, TPEs have three characteristics:<br ><br >

        1. Ability to be stretched to moderate elongations and, when the stress is removed, to return to comparable shape;<br >

        2. Ability to be processed when melted at anelevated
        temperature;<br >

        3. Lack of significant creep.<br ><br >


        TPEs offer the advantage that they can be repeatedly melt processed. No metter how many
        times you expose TPEs to sufficient heat, they will become soft and re-harden when cooled.<br ><br >


        TPEs come in pellet form in bags or gaylords, and are fed into injection molding machines
        via hoppers. The TPE pellets typically fell softer and more rubbery than rigid thermoplastic<br ><br >
        resins.


        <img src="__STATIC__/images/tpe1.gif" align="right" > TPEs are soft rubbery materials that have elastomeric
        properties. At room temperature, theyare strong, flexible
        materials. TPEs do not maintain their room temperature
        properties at high or low temperatures. The recommended
        continuous use temperature range varies among<br ><br >

        TPEs based on their copolymer composition, and should be considered in product design.<br ><br >


        TPEs prossess moderate UV resistance, but in out door applications, it is best to consider a UV
        stabilizer additive which is often compounded into the pigment. TPEs can be formulated to
        provide decent chemical resistance at room temperature. With elevated temperatures,
        TPEs normally do not have good chemical resisitance. TPEs offer good compression set at
        room temperature, but not at high or low temperatures.

        <div class="about_box_title"> Silicone vs TPE</div>
        <img src="__STATIC__/images/tpe2.gif" align="right" >In a nutshell, silicones and TPEs often have very similar properties at room temperature. In
        fact, it can be difficult to distinguish whether products are made from silicone or TPE from
        an appearance standpoint. A trick of the trade is to put the material in questionin direct
        contact with an open flame for a couple minutes. TPEs will start to deform and possibly melt,
        where as silicones will remain unaffected.<br ><br >



        Another key difference between TPEs andsilicones is the ability to recycle TPEs. Silicones,
        by their thermoset nature, cannot be melted and reprocessed once molded.<br ><br >

        TPEs and silicone are both soft flexible elastomers. Because TPEs are copolymers, a wider
        array of surface characteristics and properties are achievable. For instance, all silicones exhibit
        surface tack and tend to attract dirt and lint. Some TPEs can be formulated to be non-tacky
        and repel dirt and lint, such as TPUs. TPEs generally have better abrasion resistance properties
        than silicone.<br ><br >



        The hardness range of silicones istypically 3-80 ddurometer A. TPEs commonly
        span the 20-95 durometer A range,with a property sweet spot a bit higher than
        50 durometer of silicone,typically 70 durometer A.<br >
